PostingsReaderBase.FuzzySet appropriately configured for
each field.PostingsFormat useful for low doc-frequency fields such as primary
keys.IntIndexOutput on the provided
fileName.Lucene41PostingsFormat format for on-disk
storage, but then at read time loads and stores all
terms & postings directly in RAM as byte[], int[].FuzzySet.contains(BytesRef):
can never return definitively YES (always MAYBE),
but can sometimes definitely return NO.IntIndexInput.Reader.acceptableOverheadRatio for NumericDocValues.IntIndexInput on the provided
fileName.TermsIndexReaderBase.supportsOrd() returns true.Lucene41PostingsFormat.freqCutoff terms, otherwise uses the normal "Lucene41" format.freqCutoff terms, otherwise uses the normal "Lucene41" format.PulsingPostingsReader.PulsingEnumAttribute for reuse of
wrapped postings readers underneath pulsing.TermsIndexReaderBase.supportsOrd() returns true.String The
name of a ServiceProvider registered HashFunction
FuzzySetVersion --> Uint32 The version number of the FuzzySet class
BloomSize --> Uint32 The modulo value used
to project hashes into the field's Bitset
NumBitSetWords --> Uint32 The number of
longs (as returned from FixedBitSet.getBits())
BitSetWord --> Long A long from the array
returned by FixedBitSet.getBits()
BlockTermsReader interacts with an instance of this class
to manage its terms index.BlockTermsWriter.VariableGapTermsIndexWriter.IndexTermSelector, and stores them in a prefix trie that's
loaded entirely in RAM stored as an FST.FixedGapTermsIndexWriterCopyright © 2000-2013 Apache Software Foundation. All Rights Reserved.
